Abstract

The invention can be used in gaseous fuel combustion devices. The purpose of the invention is to increase efficiency by increasing the stability of the combustion and intensification of the mixture formation. The burner comprises a housing 1 with an upper perforated wall 2 having openings 8. The housing 1 is divided by a partition 3 with openings 4 into chambers 5 and 6 of the main and additional gas, respectively. The main gas chamber 5 is provided with nozzle nozzles 7. The main gas supplied to the chamber 5 is directed through the nozzle nozzles 7 to the combustion zone. Part of the gas through the openings 4 enters the chamber 6, from where, through the openings 8, it is also supplied to the combustion zone, forming at the root of the main torch additional torches on duty. The velocity of the gas from the holes 8 is significantly less than the rate of gas from the nozzles 7, which ensures steady combustion of additional flares and increases the efficiency of the burner. 1 l.

The invention relates to devices for burning gaseous fuel when mixed with air in the air volume and can be used in bridges where work is required in a wide range of control over fuel consumption with a high efficiency of its combustion and low toxicity. burning products.

The purpose of the invention is to improve the economics by increasing the stability of the combustion and intensifying the mixture of formation.

The drawing shows the burner, 06 in ID;

The burner comprises a housing 1 with an upper perforated wall 2, divided by a longitudinal partition 3 with openings 4 into chambers 5 and 6 of the main and additional gas communicated between themselves. The main gas chamber 5 is provided with nozzle nozzles 7 fixed on the longitudinal partition 3 and passing through the dog 6 the secondary gas. Nozzle nozzles .7 have a length equal to 0.6-1.2 widths of housing 1, the area of the flow sections of the openings 4 of the partition 3 is 0.1-0.15 of the area of the flow sections of the hop nozzles 7, and the holes 8 of the upper perforated wall 2 have an area of the passage section not less than the area of the passage section of nozzle tips 7.

The burner works as follows.

Gas from the fuel intake manifold (not shown) is fed to chamber 5 of the main gas. Through the nozzles 7, the main gas is supplied to the rhenium rum zone.

Through the holes 4, part of the gas enters the additional gas chamber 6 between the walls, from where it passes through the holes 8 to the combustion zone, forming additional duty flares at the root of the main torch.

Due to the throttling in the holes 4, the additional gas in chamber 6 is under less pressure than the main gas, therefore, its exit velocity from the holes 8 is much lower than from the main gas supply nozzles 7, which ensures steady burning of additional flares and increases efficiency.

Formula and goiter
